n. [ Cf. F. dépolarisation. ] The act of depriving of polarity, or the result of such action; reduction to an unpolarized condition. [ 1913 Webster ]

Depolarization of light (Opt.), a change in the plane of polarization of rays, especially by a crystalline medium, such that the light which had been extinguished by the analyzer reappears as if the polarization had been anulled. The word is inappropriate, as the ray does not return to the unpolarized condition. [ 1913 Webster ]

☞ This word has been inaccurately applied in optics to describe the effect of a polarizing medium, as a crystalline plate, in causing the reappearance of a ray, in consequence of a change in its plane of polarization, which previously to the change was intercepted by the analyzer. [ 1913 Webster ]
